The question now is what kind of dinosaur birds evolved from.
Since it was announced to the world, loong bird has become a star in the field of paleontology, and it has once again triggered the relevant
A heated debate about the origin of birds. The "hairy structure" of the head, neck and tail of loong birds has attracted people's attention.
Debate on the status of classification. Many paleontologists believe that the discovery of China arowana originated from birds.
The theory of small theropod dinosaurs is a strong support.
The discovery of important fossils, such as loong birds, is an important way to solve the long-standing and unresolved problem of birds in the world.
The problem of origin provided strong evidence and shocked the whole international paleontology community. Recently, "Liaoning Ancient"
The discovery of "stealing birds" also shocked the entire international paleontology community. However, the latter's "hair"
The discovery of "xian" is completely different from the former, and "stealing birds" is suspected of stealing names.
The dispute between loong and birds has settled.
When the author asked whether the loong bird dispute still existed, Ji Qiang said confidently, "China.
After more than four years of fierce debate, Dragon Bird has now reached a satisfactory conclusion. I'm interested in the dragon bird in China.
The name and viewpoint of ""are beyond reproach. The first name is' loong Bird'. Who is this?
Unable to change; Secondly, the Chinese dragon bird is a transitional type from dragon to bird, just like it.
Valuable; Third, it is the first dinosaur with primitive feathers discovered so far; Forked bone and
The unique characteristics of toes are also very rare. When I started naming, I took these characteristics into account.
Sign. Latin name is "China feathered dinosaur". "
Dr. Ji Qiang and scientists from geological museum, China, told the author: Since the loong bird was discovered,
After the fossils, geological museum was full of people. A large number of foreign scientists came to visit, a few
One delegation after another consists of ten people, divided into two schools: bird research and paleontology.
Experts from academic circles all over the world are here. These people have their own interests, and some are both interested and skeptical.
Degree, don't believe that China has this discovery that can change textbooks; Have a plenty of China's heavy hair.
Now In short, you are welcome and willing to have academic exchanges with scientists from all over the world.
So, how many loong fish fossils have attracted worldwide attention? Ji Qiang revealed: China Geology
3 museums, 2 Nanjing Institute of Geology and Paleontology, 1 ***5. Two pieces are right or wrong.
What is often precious is that they are all one-stop fish fossils with male and female dead. The female butterfly, the fossil of loong bird, is the season.
Dr. Qiang discovered and named it. After Chen Piji of Nanjing Institute of Geology and Paleontology got the first fossil,
1In August, 996, a farmer sold the female butterfly of loong fish fossil to geological museum, China.
Pavilion. Ji Qiang said to the farmer at that time: "We can't do business. You can donate to the country, the country
Give you a bonus. "So, Ji Qiang accepted the fossils on behalf of the museum and gave them to the farmer at a price of 6,000 yuan.
RMB bonus. The author asks: If someone bids for this fossil now, how much is it worth? Ji Qiang
It is said that this is a national treasure, and it will not be sold for10 million, and the scientific significance of this fossil is priceless.
People are studying the evolution of birds.
So far, Sinosauropteryx, Protoarchaeopteryx, Tailfeather Bird and North China have been found in western Liaoning.
Dinosaurs are covered with furry structures, such as floating dragons.
Since the discovery and naming of fossils such as Sinosauropteryx is a foregone conclusion, Sinosauropteryx is among birds.
What role does it play in culture? How did dinosaurs evolve into birds? This is a problem that people are increasingly concerned about.
The author asked Dr. Ji Qiang to give a brief and systematic answer. He said: A list of fossils found so far.
Ming, dinosaurs evolved into birds in a process. Late Jurassic 65438+45 million years ago, the earliest is
The featherless loong was followed by the first feathered loong bird. In the following order: Swim.
Beipiaolong, whose original feathers are 5 to 6 cm long, has flying feathers on its wings and feathers on its tail.
Tail-feathered bird, Chinese bird dragon (Long Ben), archaeopteryx with wings slightly shorter than hind legs, wings and hind legs, etc.
Archaeopteryx with flying feathers and smooth teeth, whose tail was shortened to form a coccyx and flew.
Confucius bird has more feathers than its body, no teeth, but a horny beak, similar to the Great Wall bird Confucius bird. China
The significance of the dragon bird is that it is the first dragon-like bird with primitive feathers after Huaxia dragon.
Birds are ancestors of birds. Tail-feathered birds are the earliest creatures with flying feathers found at present.
The oldest bird in the world. Archaeopteryx can glide but can't fly. Only birds after Confucius can fly.
Because of the close relationship between birds and dinosaurs, it is difficult for us to draw a clear line between them.
Line.
Ji Qiang said that the above dinosaurs evolved into a series of fossils of birds: "In addition to Confucius and Beipiao,
Dragons and Chinese bird dragons were discovered by vertebrate paleontology and ancient humans in Beijing, and the others are all geological blogs of China.
Found it in the museum. Researchers in geological museum, China, also found primitive birds, fish and two kinds of birds.
Animals, turtles, lizards, parrots, dinosaurs, primitive mammals and pterosaur fossils. , these
Stone is a rare physical evidence for studying strata and paleontology. At present, researchers of loong birds and other fossils.
The work has come to an end, and our new research topic is: What kind of carnivorous dinosaurs are birds?
Made of it? "
The author noticed that there must be something rare in Ji Qiang, a scientist with original spirit.
News materials. So I asked him again and again, and he had to say that later this year, when his thesis was in China.
After it is published in international authoritative academic journals, it will be announced to the media. If published now, it will affect its existence in China.
Publish papers in international authoritative academic journals. Later, Ji Qiang couldn't stand the entanglement of the author and told the author: bird.
At present, there are two views on which dinosaurs evolved: one is vertebrate paleontology and ancient humans.
The research institute represented by Dr. Zhou Zhonghe believes that birds evolved from dinosaurs living in trees.
The other is his own view that birds evolved from small carnivorous dinosaurs running on land.
It's over. According to the latest information available in geological museum, the closest bird is a small notebook.
Dragon. He said he didn't know what dinosaurs lived in trees were. He noticed that looking for ancestors of biological evolution
First of all, we should look for their close relatives instead of their distant ancestors. He studied the Long Ben fossil carefully after it was discovered in February this year.
Come to the above point of view.
There is a scam in the "Liaoning ancient bird" scam.
Recently, an artificial product-"Liaoning Ancient Pirate Bird" is made by splicing dinosaurs and bird fossils.
Specimens, caused an uproar in the international paleontology, and so did the news in Chinese mainland and Hong Kong and Taiwan.
Tao caused an uproar, and even some reports were inaccurate and misleading. In order to return the truth
In order to set the record straight, Dr. Ji Qiang wrote the article "The Story and Truth of the" Liaoning Ancient Bird "Incident".
Publish the whole process and secrets of facts in relevant media. He said that some young scientists are eager to show.
Himself, first participate in the scam, and then make fraud to expose the so-called "ancient bird" scam. Actually, it's a scam.
There are also scams, which most people only know and don't know why.
Dr. Ji Qiang told the author: "Liaoning ancient bird" consists of three parts: one is Confucius bird's
Reptiles' bodies, heads and dinosaurs' tails. Last year 165438+ 10, National Geographic.
The magazine published an article entitled "Did Tyrannosaurus Rex grow feathers?" The article believes that "pirate birds" even
The "missing link" between dinosaurs and birds provides the most direct basis for the origin theory of birds and dinosaurs.
It is reported that a young scientist engaged in paleontology research pointed out that "Archaeopteryx" is a fake fossil.
Corrected the mistake of National Geographic magazine.
In fact, this young scientist participated in a Sino-US cooperative project to study fossils of "ancient birds".
After investigation, the two sides agreed to hold a special meeting at the headquarters of the National Geographic Society in Washington, D.C. from June 5 to June 5, 1999.
Great Discovery held a grand press conference and announced the news in National Geographic magazine.
Let's go On the other hand, scientists from the United States and China have stepped up their efforts to write academic papers and contribute to the British magazine Nature.
Magazine (young scientists are the fourth author of the paper). However, there is an unfortunate news from England.
Nature magazine refused to publish their academic papers for the simple reason that it was in the process of paper review.
Two experts found that the fossil specimens were pieced together. It is puzzling that some people
Now that you have been caught in the "ancient bird" scam, how can you become the person who exposes the "ancient bird" scam?
And then what?
Having said that, the author can't help but interject: "You expose the scam in the scam and are not afraid of being sued."
Sue you? Ji Qiang replied: "International cooperation projects, press conferences and academic publications are well documented.
Yes, foreign experts also told me about it, and I have made enough psychological preparations. I dare
Yu stepped forward and revealed the truth by his real name in the media, precisely to safeguard the dignity of science. "
Dr. Ji Qiang also told the author that as early as June 1998, he was a fossil dealer in Jinzhou, Liaoning Province.
I want to sell fake fossils to researcher Chen Piji of Nanjing Institute of Geology and Paleontology. After observation, Chen Piji approved it.
This is a fake fossil specimen, which categorically rejects the fossil dealer. When he was found to be human
When the worker made fake fossil specimens, he took photos. Ji Qiang said, "In June this year, researcher Chen Piji also
Showed me the photos of the fossil specimens of' ancient birds' taken at that time. I compared it with National Geographic.
The pictures published in the magazine were compared and verified, which proved to be the' Liaoning ancient bird' smuggled into the United States.
Stone specimens. Therefore, it is researcher Chen Piji who really discovered the false fossils of' ancient birds'. "
1February, 999, the fossil was smuggled to the United States at the "Tucson Minerals and Fossils Expo".
It was bought for $80,000 by a staff member of Brandon Museum in Utah, USA. In recent years,
China and Canada have a say in the origin of birds, but the United States has no say. Got the "ancient"
After "stealing birds" fossil specimens, the United States gained treasure. 1999 March, National Geographic Society, USA
Send letters to Dr. Ji Qiang, Academician Zhang Miman and Academician Qiu Zhu Dingyan from vertebrate paleontology Institute of Paleoanthropology, China Academy of Sciences.
The researcher invited scientists from the United States and China to cooperate in studying this fossil. Because Ji Qiang has different opinions on the treatment of fossils
The interests of the United States, so no longer looking for him, and unilaterally cooperate with vertebrate paleontology and the Institute of Paleoanthropology.
Touch. Ji Qiang said: "This is a deal focused on the United States. I think the principle belongs to
In principle, a transaction is a transaction. "
Ji Qiang pointed out that commercial transactions are involved in scientific research at present, and fossil counterfeiting and smuggling are harmful to science.
This research has had a serious negative impact.
